Funny that for the longest time there is 1 Pioneer flasher now everybody is working on one
https://freemkv.org/firmware/find/
I have MediaTek flashing down (as well as modification).
Pioneer flashes come in 2 files: Kernels & Normals. I have around 200+ Kernels, 900+ normals and 100+ different models. These will be landing on the website soon for FREE download.
My flasher is fully working on MediaTek and being tested now on Pioneer. Again, free and open source. So please contribute to the code
